The Great Pyramid

Egyptologists conclude that the pyramid was built as a tomb for the Fourth Dynasty Egyptian pharaoh Khufu and estimate that it was built in the 26th century BC during a period of around 27 years.[3]

Initially standing at 146.5 meters (481 feet), the Great Pyramid was the tallest man-made structure in the world for more than 3,800 years. Throughout history, the majority of the smooth white limestone casing was removed, which lowered the pyramid’s height to the present 138.5 meters (454.4 ft). What is seen today is the underlying core structure. The base was measured to be about 230.3 metres (755.6 ft) square, giving a volume of roughly 2.6 million cubic meters (92 million cubic feet), which includes an internal hillock.[4]

The dimensions of the pyramid were 280 royal cubits (146.7 m; 481.4 ft) high, a base length of 440 cubits (230.6 m; 756.4 ft), with a seked of 5+1/2 palms (a slope of 51°50’40”).

The Great Pyramid was built by quarrying an estimated 2.3 million large blocks weighing 6 million tonnes total. The majority of stones are not uniform in size or shape and are only roughly dressed.[5] The outside layers were bound together by mortar. Primarily local limestone from the Giza Plateau was used. Other blocks were imported by boat down the Nile: White limestone from Tura for the casing, and granite blocks from Aswan, weighing up to 80 tonnes, for the King’s Chamber structure.[6]

There are three known chambers inside the Great Pyramid. The lowest was cut into the bedrock, upon which the pyramid was built, but remained unfinished. The so-called[7] Queen’s Chamber and King’s Chamber, that contains a granite sarcophagus, are higher up, within the pyramid structure.

The Great Pyramid

Considered by the Greeks to be of the “seven wonders of the world,” the Great Pyramid at Giza consists of 2 million limestone blocks, each weighing up to 15 tons. The pyramid is aligned true north, and the base forms an almost perfect square. The base is 756 feet long on each side covering 13.1 acres.

Five major European cathedrals could all fit inside. The great pyramid is 482 feet high, 178 feet taller than the statue of liberty, and the only seven wonders still standing.. How the Egyptians moved stone blocks, some being quarried from more than 400 miles away has baffled scholars.
